Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication, forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts.
Our Low Cost Oil Change includes: up to 5 quarts of high grade oil, filter and our safety inspection!
Most cars on the road today use multi-grade oil — one that can work efficiently in cold and hot weather. A multi-grade oil is rated by two numbers, such as 5W-30.
The Oil Classification System
In a multi-grade oil, the first number indicates how the oil will flow when it is cold. The lower the number, the lighter the oil and the better it will perform at lower temperatures. The second number indicates the thickness of that same oil at high temperatures.
Oil filters are designed to trap foreign particles suspended in the oil and prevent them from getting to the engine bearings and other parts. Filter media is also important. Some filters are engineered with synthetic filter media. The synthetic media is said to be capable of trapping small contaminants over a longer period of time.
Not all motor engine oils are 100% petroleum. Synthetic oils, which are primarily chemically compounded lubricants, are also available.
Why Viscosity Is A Concern
During cold starting, only a small amount of oil is present in the upper parts of engines. To lessen the friction when upper engine parts, such as the valve train, pistons, overhead cam and cam bearings, scrub against each other, a lower viscosity allows the oil to reach the components more quickly.
Why 5w-30 And 5w-20 Oils Are So Popular
Many vehicles today leave the factory with 5W-30 or 5w-20 engine oil. Vehicle manufacturers recommend them because they are lighter oils that perform well in a range of temperatures and help improve gas mileage.
